Hi Pinku,

>> the date format in one database is this 31-OCT-2008 and in other is this 2/1/2008
OK, which do you want to use?
READ THIS:http://www.dba-oracle.com/t_nls_date_format_sysdate.htmOK, adjust the NLS_DATE_FORMAT parms to match.
READ THIS CAREFULLY:http://www.dba-oracle.com/sf_setting_parameters_tips.htmIn each init.ora (or spfile) change NLS_DATE_FORMAT='dd-mon-yyyy';
